[closed] How to Remove the header from posts in Untitled Theme? (4 posts)

Hi guys! I am a bit new on WordPress. I installed the untitled theme for my blog earnsmartonline.com and currently, the header appears on all posts, which makes it to overlap with the featured image.

I would like the header to be on the home page only but not on the posts (blog page). Each post should have the featured image in place of the header just like on this site that uses the same theme: allthingsebonybrown.com. Any simple way to fix this issue? I really appreciate your feedback :)
